Wheal Anna Maria Calciner Complex
Highlight • Structure
It was named after the Duchess of Bedford!
Her main workings were on the ‘Main Lode‘ (the largest sulphide deposit in southwest England).
When its rich copper waned, Devon Great Consols became the largest arsenic mine in the world because the margins of the copper-rich lode were dominated by arsenopyrite.
In 1860 the copper lode at Anna Maria was up to 45 feet wide and yielding up to 80 tons per fathom, but by around 1880 the copper boom was over. Thankfully, arsenic production sustained the mine into the 1900s, until the company folded.
Arsenic ore, unlike copper ore, was refined on site using the ‘calcination’ process – and at Wheal Anna Maria they yielded over 72,000 tons of refined arsenic! – Whoop!

View from Blanchdown Wood
Highlight • Forest
Look down and you will see the spoil heaps of the Great Devon Consols, the name of the mine once situated here. First copper and then arsenic was mined here and signs of the long gone industry can be seen throughout Blanchdown Wood.

Morwell Rock
Highlight • Natural Monument
Down below the rock, the sharp bend in the River is known as the Impham Turn, where the river runs almost directly into the rocks but makes a sudden 90 degree turn just beforehand.
It is possible to climb Morwell Rock, with the right training, experience and equipment. Although some of the climbing routes are now overgrown a few do remain.
